Well, I wired it up sort of like your circuit here. Except I have a 220? R for the green, and a 330? for the red, to try to balance the intensity a bit. Kinda makes me go meh as a quickie visual indicator of over/under temp, which is where I was hoping to use this -- right now, I'm using a pot as a proxy for a temp. sensor. The shading is somewhat poorly mixed, so the yellow midpoint doesn't really look yellow.

Might be I'll need to go for a RGB LED, so I can ramp the color more clearly away from the OK state.

But I didn't let any smoke out.
